It could make Sooloos the cheaper long term option, however you may be assuming that you won't be wanting to replace Sooloos hardware as the product becomes more powerful. There are also considerations re: hardware faults that should be factored in. Roon will also have these, but there are more flexible workarounds with Roon.
